Researchers develop world’s first self-healing polymer

The researchers, from the CIDETEC Centre for Electrochemical Technologies in San Sebastian, Spain have created the world’s first self-healing polymer that spontaneously and independently repairs itself without any intervention.

How does the self-healing polymer work?

The scientists developed the self-healing thermoset elastomers from common polymeric starting materials using a simple and inexpensive approach. A double decomposition reaction of aromatic disulphides, which naturally exchange at room temperature, causes the regeneration. The polymer behaves as a Velcro-like sealant or adhesive, displaying an impressive 97% healing efficiency in just 2 hours.

What could be the use of self-healing polymer?

The new material could be used to improve the security and lifetime of plastic parts in everyday products such as electrical components, cars and even houses.
